The OPTEC-3600 circular dovetail mount is used for the large TCF-S3 focuser, Pyxis 3" rotator, the IFW-3" or the Perseus 4-port Instrument Selector. These mounts allow easy connections from most any telescope. One side has a telescope-specific thread or dovetail and the other side presents the 3.6-inch diameter Optec dovetail mount.
